STEAM-ELIMINATOR.

SPECIFICATION forming part of Letters Patent No. 600,921, dated March22, 1898. Application filed Tune 21,1897. Serial No. 641,738. (Nomodel.)

.To all whom. it may concern:

Be it known that we, JOHN LLOYD, WIL- LIAM LLOYD, and RICHARD O. JONES,citizens of the United States, residing at Pittston, in the county ofLuzerne and State of Pennsylvania, have invented a new and ImprovedSteam-Eliminator, of which the following description, in connection withthe accompanying drawings, is a full, clear, and exact specification.

The invention relates to improvements in steam-eliminators or apparatusfor the purpose of eliminating water, entrained moisture, grease, oil,or impurities from steam at any pressure and automatically dischargingthe water, entrained moisture, grease, oil, or impurities into theatmosphere or into any vessel provided for the same. These objects areaccomplished by the mechanism illustrated in the accompanying drawings,in Which- Figure l is a vertical section of the entire machine; Fig. 2,another vertical section at right angles to the section shown in Fig. l,but having the throttle and float removed to show more clearly thearrangement of the steam-ports. Fig. 3 is a horizontal section on lineWX, Fig. 2. Fig. l is a horizontal section on line Y Z, Fig. l. Fig. 5 isa detail end view of the throttle and iioat mechanism. Fig. 6 is a sideelevation of the same. Fig. 7 is a plan view of the same. Fig. 8 is ahorizontal section of throttle, showing arrangement of ports.

Similar letters refer to similar parts throughout the several views.

In the improved steam-eliminator, O is a casing or reservoir designed tocollect the Water, entrained moisture, grease, oil, or impurities orwhatever may be eliminated from the steam and to hold same untilliberated by the outlet-valve. The casing O is provided with the steaminlet and outlet openings (shown at A and B) and the outlet-opening fordischarge, (shown at 0,) also the corrugated surfaces of sharp points b,also the annular rings or shoulders o2 and e2 and the brackets e3, alsothe steam-pipes 3, g3, and as, also the steam-cylinder f, also thepartition-webs O2 and O3, designed to close the lower portion of theoutlet-chamber from the rest of the casing.

K is a cap or cover secured to the casing O, but removable at will. Tothis cover are secured the baffle-plates a, which have corrugatedsurfaces of sharp edges designed to eliminate the Water, entrainedmoisture, grease, oil, or impurities from the steam. Underneath thesebaflie-plates a is a perforated plate c, made in halves and resting uponthe annular ring c2, designed to prevent the steam from siphoning orpicking up the water after it has been deposited in the reservoir.

The hand-hole cover d, secured to the casing O, but removable at will,facilitates free access to the working parts of the machine for repairor adjustment. The cover d contains the steam-ports t', y, and a,leading into and connecting with the steam-ports t2, y2, and z2 in thecasing O. The perforated plate e, made in halves and resting upon theannular ring or shoulder e2, is held in place by the brackets e3. Thisperforated plate e is designed to break the water into small portions asit goes out, scattering it over a larger area than that of theOutlet-valve, thereby preventing the steam from blowing through the bodyof Water and escaping. To the steamcylinder f is iitted the piston g, towhich is secured the rod h, to which rod is secured the outlet-valve 7c.p

To the cover d is secured the throttle T, Figs. 5, 6, 7, and 8. Thepressure-plate p2 is secured to the throttle-seat p and is designed torelieve the slide-valve 'u from fric-tion due to steam-pressure. Thethrottle-seat p contains the steam-ports q, r, and s, which lead fromthe cover d to the slide-valve fv, in which is the steam-port '02. Amovement to the left of the slide-valve 'v thus opens to each other theports q and fr, While a movement to the right of the slide-valve u opensto each other the ports r and s, closing to each other the ports g andr. The slide-valve o is operated by the float F through the rod t and'the pin w, the rodi being fulcrumed on the pin u, secured to thethrottle-seat p. The float F, resting upon the surface of the water inthe casing O, rises and falls with the surface of the water, thusoperating and controlling the movement of the slide-valve fu.

The operation of the mechanism in the improved steam-eliminator isdescribed as fol- IOO lows: The steam, entering the casing C at A, takesthe direction shown by the arrows,Fig. 3, passing over the baffle-platesa and the points b, and passes out of the casing at B. In its passageover these sharp points the steam is relieved of loose water, entrainedmoisture, grease, oil, or impurities, all of which fall through theperforated plate c into the reservoir beneath. The outlet valve 7cbeingclosed by the steam-pressure in the casing, the water rises to the levelof the upper position of the iioat F, as shown in Fig. l. The power thenexerted by the float, due to its displacement, moves the valve fu to theleft, opening the port q to the port fr, allowing steam to pass into thepipe 3 at D, thence through the cover d, the throttle, and the pipe yainto the cylinder f. The pressure of the steam in the cylinder f forcesthe piston g forward, and with it the outlet-valve k, when thesteampressure in the casing forces the confined water through thevalve-seat j and the opening 1t and thence out of the machine at o. Whenthe surface ofthe water has dropped to the level of the lower positionof the float, (shown by dotted lines, Fig. 1,) the float moves theslide-valve i: to the right, closing the port q to the port r andopening the port fr to the port s, making a free open exhaust throughthe pipe ys, the coverd, the throttle, and the pipe ,z3 out of themachine at G. The piston g being then relieved of the steam-pressurebehind it, the outlet-valve 7c is again closed by the steam-pressure inthe casing, when the water rises again, thus repeating the operation.

It will thus be seen that the mechanism is entirely automatic,discharging at intervals whatever may be eliminated from the steam.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-
